It's a lot easier with a re2c-based lexer, but porting the flex scanner to re2c is the definition of "oh-my-god-almighty" complex and until someone just does it, it ain't gonna happen. The other hackish alternative is to add rules to the parser with reserved words (T_FUNCTION T_IMPORT as well as T_FUNCTION T_STRING, etc. etc.), but this slows down the parser and adds unnecessary duplication.
